156B Week 1

Overview of Status of Analysis, Design, Fabrication, Tests, etc.

• • Electrical system economically viable

  • Purely mechanical system sufficient for shallow water sources

Accomplishments from Previous Week

• • Purchased pump

  • Completed preliminary electric bike research

Goals for Next Week (list names after each item). Use specific and measurable objectives.

• • Familiarize ourselves with sponsor-provided solar kits

  • Finish individual component analysis for:

    • Braking system (Derek)

    • Pump (Jessica)

    • Stand (Dennis)

    • Filter (Kyle)

    • Electric motor to drive bike (Jaime and Brandon)

Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)

• • Sponsor meeting in person 3/23/17

    • Primary water source= surface water --> Action: choose water pump accordingly

    • Implement solar panels for energy --> Action: Compare integration into cart design (portable panels) vs. tri-pod assembly (stationary panels)

    • Mobility challenge with terrain in Nicaragua and Ghana --> Action: focus on optimizing power over speed with bike/cart system (i.e. motor choice)

    • Braking=important! --> Action: look into breaking systems for individual component analysis

    • Secondary goals: D.lights, water filtration system --> Action: individual component analysis

Instructor Comments from Last Meeting and Actions Taken to Address these Comments  (indicate date of comments and if via email or in person)
